The Salt Mines

A big, squarish couple of maps sets in some sort dungeon place with some abstract looking caverns (one sets in a small canyon and the other in a cramped ice cavern) and having the most infested swamps i've seen so far in Hexen, near to a level of complete ridiculousness. Also includes some pretty weird choices

Also, the exit can't be activated for some strange reason in zandronum.

Not a fun or good level, neither the really rare good parts like the staircase and the lighting works can save this map from being just not that good imo.

These two Hexen maps (which should be loaded together) will appeal to the game's fans. Note that if you play as the Fighter, then you'll only have melee weapons until quite some way into the game; I recommend the Mage. You have a good range of those that Hexen has to offer (including an ice area, which I found quite difficult) - I'm not sure what the logic that links it all together might be, or why it all fits with the idea of salt mines, but I suppose it's better this way than it being too monotonous.
